I Original application fi led March 22, 1905, Serial No. 251.374.Divided and this application filed November 26, 1906. Serial To all whomit may concern:

Be it known that I, CHARLES RoUsE, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and StateofPennsylvania, have invented certain new and useful Improvements'inSuports for Conveyor-Belts, of which the folowing is a specification,reference being had therein to't'he accompanying drawings.

My present invention relates to ,improve ments in supports forconveyer-belts; and the main ob ect of my invention is the rofanlarly-arranged rollers the supporting-sur aces of which conform to thenatural curvature bf the belt, the central roller being made in a seriesof independent sections. With this object in view attention is invitedto the accompanying drawings, in which- Figure 1 is a horizontalsectional view taken through the support, showing my construction. Fig.2 is an elevation thereof.

Referring to the drawings, the numeral 1 designates the brackets, whichare arranged in pairs and so disposed that the inner projections 2oppose each other, while the outer upwardly-inclined projections 3extend outwardly in opposite directions.v The bore 4 is formed in theseprojections, terminating in long the enlar ed portions for the receptionof the tubular sIiaftsfi and 7, the shaft 7 connecting the bracketstogether and having mounted thereon a bushing or bearing 8 for thereception of the central concaved roller or pul- "ley 9 and the twoouter rollers or pulleys 10,

whose outer surfaces are inclined inwardly and aline with the concavedsurface of the central pulley. The brackets '1 are rovided with a smallprojection 2, the ho low shaft extending a distance in the bracket, soas to rovide proper bearing-surface for the these three pulleys.

In order to properly oil the rollers or pulleys 9, 10, and 15, theshafts 6 and 7 are rovided with openings 8 and 14. The ro lers orpulleys 15 are rotatably-mounted upon the bushings 14 and are secured inplace by means of the shoulder 16, carried by the grease-cups 17, whichare secured to the outer end of the shafts 6 by means of the setscrews18. These pulleys 15 simply provide ushing upon which are journaled asurfa'cewhereby the outer edges of the belt concaved in cross-section,While the central and outer sections of the center pulley provide areater inclination and allow the central ro ler or section, which issmaller than the other ulleys, to revolve at a greater s eed, as t ecircumference is smaller than t e others. I

I have found by experience that when a single central pulley is employedthere is a great amount of friction, because of the central pulley beingsmaller in diameter than the outer pulleys. It must revolve faster orslide or cause a sliding motion a ainst the surface of the belt farthestfrom t e center, and I have therefore designed the present constructiont0 overcome this difficulty.

From the foregoing description, taken in connection with the drawings,it is evident conveyer su ort.

What I 0 arm as new, and desire to secure by Letters Patent, is v 1. Asupport for a conveyor-belt, comprising a plurality ofangularly-a'rranged ro lers having the supporting-surfaces thereofconforming to the natura curvature of the belt thereon, the centralroller being made in a series of sections free to rotate independentlyofeach other and having their surfaces upon a curved line, the angularrollers being of the same diameter throughout their lengths.

2. A supporting meaifs for conveyer-belts, comprising a plurality ofarigularly-arranged series of sections and provided with a concavedsurface, the sections of which are journaled independently to each otherand are inclined so that their surfaces form a connectin -link betweenthe curvature of the central ro ler and the angularly-arranged rollers,said angularly-arranged rollers being cylindrical in shape and of equaldiameters.

3. A support for conveyer-belts, com rising a pair of brackets,outwardly-inc ed upon each, a central bearing connecting the bracketstogether, and a central roller composed of a series ofindependently-rotatable sections mounted upon said connecting-bearmg. I
